Itinerary Review: Paris-Strasbourg-Zurich-Lucerne-Salzburg-Hallstatt-Munich in 15 Days

I would suggest taking one day from Salzburg and one day from Hallstatt and adding two days to Munich.

Munich is an important city that's worthy more than 2 days. There are just so many sights to see, and it's such a fun place.

Seems like you could take a more direct route to Luzern and skip transfer in Zurich.

I agree with above. saw all the sights in Strasbourg in a day. take a day trip to Lake Konigsee and the boat trip around the lake from Salzburg. there is a bus that takes you there

Yes, but if you're in Strasbourg for 2 days, you can day-trip to wonderful Colmar.

I think adding a day to Munich is a very good idea. You will need a full day to see Neuschwanstein (it is a 2 hour train ride each way from Munich). Dachau is much closer and can be fully covered in half a day. Consider planning something light hearted that afternoon such as a trip to the Engligh Garden. You also want to make sure that you have a full day to explore Munich on its own. It is a lovely city. Rather than taking a day away from Paris, I would consider shortening your stay in Salzburg. We spent 7 days n Paris last year and it was not enough.

Look at doing the itinerary in reverse order. You could fly into Munich and then buy a Bayern Ticket that will cover your train fare from the airport all the way to Salzburg. Maybe 3 nights in Salzburg that includes a day trip to Hallstatt. Back to Munich for 4 nights (includes day trip to Neuschwanstein). On to Lucerne, Strasbourg and Paris. [Most trains between Lucerne and Strasbourg go via 1 change in Basel.] My preference would be to omit Strasbourg and add 2 more days to Paris.
